Overview
The Schlegel Elektrokontakt STI (SKU: STI) is a precision-engineered momentary pushbutton switch designed for industrial control systems. This switch features a 2.3 mm travel distance, delivering clear tactile feedback for operator confirmation during actuation. It is engineered for a standard 22.3 mm round panel cutout, ensuring compatibility with existing control panel designs and machinery layouts. Connection is facilitated via 2.8 x 0.8 mm Faston terminals, providing secure and efficient electrical terminations for reliable signal transmission. A switching position indicator is integrated for visual confirmation of contact state, enhancing operational clarity in control applications. Typical uses include machine control panels, automation equipment, emergency stop systems, and any scenario requiring a momentary electrical contact with reliable actuation and feedback. The STI’s silver bezel finish provides a professional appearance while maintaining durability. Its compact design and standardized mounting dimensions allow for easy integration into control panels without requiring custom modifications. The switch’s momentary contact type ensures temporary signal activation, making it suitable for momentary pushbutton functions in control circuits.
